` i913. Serial No. lllv c and I. do declare the fr'illowing," to be a full,

clear, and exact description of. the invention, such as will enable others skilled in the art to which it -a-ppert-ains to make and use the saine, reference being had to the accompanying drawings', and to the letters and figures of reference marked thereonJ which I form a part of this specification.

My invention relates to car couplers, and has for its object to provide a coupler which shall embody' so far as possible the maximum yof 'strength with the minimum. of metal and in which the component parte will be retained in their respective positions or places without liability of becoming accidentally displaced or lost, and under which the movable parts willoe effectively shielded or protected against injury or damage from the outside.

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter particularly described and then'- sought to be clearly deiined by the claims. whereby the coupling link not in use may he safely housed sons to be protected from injury and be prevented from interfering with the proper action of other parts; also in features of construction 4whereby the coupling pin of one car is permanently retained in operative relation .to associated lparts so that the coupling pin remains alwaysconnected with the draw-head while the link of the other car to be' coupled 'may be readily engaged by the coupling pin of 'the car;v also lin features of construction in which the coupling pin may have a `movement to either side of the center oi the openings formed in the draw-head to receive th coupling-pin so that the pull on the coupling pin may be in a moredirect line with longitudinal sills of a car-and the couplersbe afforded a greater range of side,l movement v'than heretoform and also to acilitate the coupling of two cars.

Reference is to be had to the accompany ing drawings forming a part herccg', and in Figure l is e perspective of the -drew-lieed paimo the coupler; Fig, 2 ati-vertical lonagitudinal section through `the coupler, the coupling pin'being in fulllines; Fig.. 3 a

horizontal central section through the coupler; Fig. 4l a vertical,A cross section through the coupler, tli e `links'jand pin being in fulllines. c Y' ln thedrawing the numeral .l designates a dravi/head'having a rearwardly extending4 shank 2 .which will llt in arsuitable housing wise' secured to a car. l

The draw-head'is made with a recess or chamber 3 beneath itstop and preferably formed by a depending flange el, said cham-V ber extending crosswise of the'draw-head and adapted to receive and shield a perrnanent'ly attached coupling;y link 5-so that when said link is not in use and twocars. are coupled together said link will be con ber and shielded from injury and prevented Y from projecting outside 'of the draw-head when the cars uncoupled from another car,"

said lower lrecess or chamber extending crosswise of the draw-head similarly to the alors-mentioned upperrecess or chamber. The space 8 between ,the depending flange e andthe upper extending flange' 7 is lessy (not shown)` adapted to be bolted or other indepth than the. ,combined thickness of I two coupling links' andvl-so that.when two cars are coupled together the perma-y nently attached link lyingwithin theupper recess or chcmber cannot pass or drop .below the' lowen edge of the flange @fnd thus the idle vlink is. kept inthe top chamber` l so that cannot pass throughthe space'gS and proiect outside of the draw-headiwhen two cars are coupled together. It will valsobe obserimd l:irornan inspection of Figs.'V 2l andfi of 1e drawing that i'the-active link 15 or the link Iin use tilt'as'shownin the illustration'it's inner en'd will'press upwardA beneaththe idle link and tend ytoh'oldthe idle link within its '-recess orf".`chamber as ci the draw-head the holes or slots 9 and 10 oaimed respectively in the top and bottom embers ci the jaw of the draw-head toree the coupling pin 1l, said oblong holes "ing to opposite sides of the longitudil center line of the draw-head so as to Ovide for the coupling pin to lie either in the center so that the pull on fthe coupling tudinal axis of the coupler and thus lessen the diagonal direction of pull on the' coupling pin which occurs when cars travel or curves. This feature of construction also s it possible to more readily and easily e 'two cars together-When the couplers not in exact alinement with each other l also allows, the couplers greater side f or movement under conditions in which 2G .ity is desirable to provide' for the same. ,y L another feature oftheinvention lies-in perconnectingfthe coupling pin to the orliead l2 at its 'lower end and encircled by washer i3 which is free to slide on the coupling pin but not to pass over the shoulderor head 12 at one end oi' the pin, and is incapable of passing through the i0 coupling links, the opposite or upper end of the pin, after the pin is placed irl-.position and passed through the Washeryand the idle link, being provided With a head ll which may he threaded or secured by a pin or /15 otherwise to the coupling pin so as to rest en top of the draw-head about tliefopening 9 torn d therein, the head being of such di- :fnensions that it cannot pass downwardly through the opening 9. The idle link and` 5G washer are thus attached by the coupiling pin to the draw-head, andthe coupling pin is thus connected to-the draw-head so that while it .may have a vertical movement it cannot become detached from. the draW head and yet it is free to be passed through the link which for the. time serves as the coupling link between the tivo cars.v The' side-walls, either upper or lower, or both, oi the lower opening 10 for the coupling l0 pin are beveled or flared so as to facilitate the lower shouldered end of the coupling pin being directed they QlSy l the center of the holes. or to either slde ci may be in a more direct line with the l passage therethrough in either lifting lowering the couplingpin.

The particular ,features olf consti-nothin f described provide a coupler possessing vseveral advantages specilied, and besides giving the maximum strength also make i Vpossible to more conveniently manipulat the parts in coupling and uncoupling.

By draw-head as used herein it is not to be understood as confined to a two-part drawhead' construction as'soine features oif 'the in ventionare equally applicable Whether the draw-head be a one-piece coupler or more than one. y
